Yeah, I think we do have a problem with concentrating our focus and confirming kills. I need to get in the habit of calling out weak characters as I'm trying to get them, as well as paying attention to other people's callouts and grouping up on enemies. That was our biggest fault - they were focusing hard on me as Winston and then whenever I got high charge as Zarya they all turned focus on me too.
And yeah, that random was not meshing with our group at all.
Another side note: my three best/most played characters this comp season are D. Va/Zen/Lucio and you guys managed to lock me out of all three both games. That's my only explanation for my subpar Winston.
EDIT: Went 1-1 with GAF stack and 2-0-1 in solo queue tonight. Not an awful showing. The draw was an intense hold on Hanamura where we held them for almost four minutes after we captured the second point on Attack in overtime. It was dicey but we managed it. Still hoping to get above 2600 before season end, but if they implement the new rules and my placements aren't awful, I should hopefully land starting in Platinum for the first time for season 6 and maybe I can finally march on to Diamond.
